Re: Collecting games with players at specific FIDE ELO level

I expanded my utility minElo to perform extractions based on 2 Elo ranges. I think it works properly, but I cannot guarantee it. So please pm any errors to me. Here is the download link: http://www.orbitfiles.com/download/id1843401880.html Here are some usage examples: To extract all games with BOTH...

Re: Collecting games with players at specific FIDE ELO level

minelo only works with pgn files. It is my understanding that chessbase proprietary data files can be converted to/from pgn files through a chessbase gui or through their proprietary database program.

pgn files are not proprietary and that is why I only work with them.

Re: Collecting games with players at specific FIDE ELO level

I have a utility tool that extracts games where BOTH players are at/between specific Elo levels. I don't know if that will help you since you only want ONE player at/between a specific level. The utility tool is called "minelo" and it is easy to use in a Dos command window. For example: minelo alpha...

Re: CCRL update (1st September 2007)

I think that draw analysis is very bad to decide if engines are in the same family. I see no reason to assume that there will be more draws between program A and itself relative to draws between 2 other engines that have the same playing strength. For example I can imagine a small number of draws b...

Re: CCRL update (1st September 2007)

Hi Kiril, If both "ponder hits" and "draw analysis" point in the same direction, then there are likely to be 2 similar thinking engines. Are there any "control" experiments with "ponder hits" to establish reference points for the stats?. Like calculating "ponder hits" with two identical engines, or ...

Re: CCRL update (1st September 2007)

Hi Kiril, "Ponder hits" and "draw analysis" both attempt to see if 2 engines think alike. Each is not definitive proof as each can contain inaccuracies. But perhaps together, they are more persuasive than either alone. "Ponder hits" as I understand it, can have inaccuracies due to the differing amou...

Re: CCRL update (1st September 2007)

Hi Graham, I decided to do a "draw-rate" analysis of current 40/40 CCRL games between Strelka versions and versions of Rybka, Toga and Fruit. I recall reading that Strelka may be based on those engines. I noticed that CCRL considers Strelka games v Rybka, Toga and Fruit to be "inter-family" games. B...

Re: The Dead of the Fish?.....

It is possible that AC gained some insight from the Strelka revelations. If so, the implementation of those theories into Zap should make it much more competitive with the Fish.

Re: CCRL update (25th August 2007)

Hi Graham & Kiril, In the 40/40 group, I wonder why testing was halted for Naum 2.2 64-bit 2CPU. It only has played 31 games. And based on that, its rating is actually higher (3013 to 3004) than the 4CPU version which has played 266 games. So by your rules, because of insufficient games, the 4CPU ve...

Re: CCRL update (18th August 2007)

Hi Graham,

I cannot seem to find the link on 40/4 to download "all games". I found it for 40/40 and 40/12. Please check.
